Problems solved by technology

[0002] The application of cables can be seen everywhere. At present, the cables used for pipeline leakage detection mostly adopt a two-core structure. For the detection function, on the one hand, it is used as a sensor, and on the other hand, it needs to transmit the data detected by the instrument to the central processing unit. Some pipelines are overhead on the ground, and there are monitoring video units, and power supply is required. The two-core structure cannot meet the above requirements. If a separate line is added to meet the requirements, the cost will increase too much, which will create a big problem for consumers. At the same time, because the hot water overflowed or the steam sprayed out can reach a maximum temperature of 250°C-300°C when a leak occurs, the outer sheath of a conventional optical cable cannot withstand such a high temperature

Abstract

The invention provides a communication optical cable for pipeline leakage detection. The communication optical cable includes an outer protective layer, a data transmission cable, a temperature testing cable, and a live wire cable, the outer protective layer coats the data transmission cable, the temperature testing cable, and the power supply cable core, the temperature testing cable is a detection type multi-mode fiber, one end of the live wire cable is connected with an external power supply device, the other end of the live wire cable is connected with an external detection instrument, one end of the data transmission cable is connected with an external detection instrument, the other end of the data transmission cable is connected with an external data central processing unit, one end of the temperature testing cable is connected with the external detection instrument, and the other end of the temperature testing cable is fixed on an external wiring device via a tail fiber. The temperature testing cable and the communication optical cable are integrated for use, so that the structure is simplified, the cost is maximally reduced, and the signal transmission efficiency is improved.
